FMF Q-Series

- That’s why we’ve developed our Q Series: 2-stroke and 4-stroke competition mufflers with full power at 92 dB!
They offer an improved performance characteristic and at only 1.7 and 2.8 kg respectively are lighter and more compact than most series-production mufflers.
We all know that we have to reduce noise emissions in order to give our sport a future, and the inhabitants of our forests are also happier if we are a bit quieter!
Less Sound = More Ground!
